Studies reveal sources of fog drip in tropical rainforests

摘要

The frequent occurrence of radiation fog appears to play an important role in the hydro-logical cycle of the tropical rainforests in Xishuangbanna. The fog drip, as compared with the other waters, was consistently more enriched, and yielded a higher value. Radiation fog appears to be produced mainly through evaporation from a pond, river, and soil plus forest evapotranspiration, especially during a dry season.
